The time course of antibody synthesis during syphilis was studied in experimentally infected rabbits. A rapid antibody response was seen; the rabbits became positive in both the rapid plasma reagin (RPR) test and Treponema pallidum haemagglutination assay (TPHA) by nine days after infection. Treponemal immobilising antibodies were also seen as early as nine days after infection. Antibody inhibi...
Members of the family Enterobacteriaceae are major cause nosocomial infections, including approximately 70% gastrointestinal 60% to urinary tract infections (UTIs), and septicemias. Since 1990, members have emerged as predominant pathogens causing UTIs. In this study, we performed phenotypic testing virulence factors in uropathogens. A total 118 uropathogens belonging were isolated from suspect...
Treatment for maternal syphilis with single-dose benzathine penicillin (2.4 million units intramuscularly) is being implemented in many parts of sub-Saharan Africa. To examine the effectiveness of this regimen, a prospective cohort of 1688 pregnant women was recruited in Tanzania. Birth outcomes were compared among women treated for high-titer (n=133; rapid plasma reagin [RPR] titer > or = 1:8 ...
Two hundred and eighty Rapid Plasma Reagin (RPR) positive sera with an emphasis on cases with negative and borderline positive Treponema pallidum haemagglutination assay (TPHA) results were selected. Modified TPHA (M-TPHA) and fluorescent treponemal antibody absorption (FTA-abs) tests were used for comparison. One hundred and twenty five samples were TPHA negative, of which 78 and 69 cases were...
A sensitive immunoassay procedure for the detection of the thrombopoietic-stimulating factor (TSF) has been developed. This procedure Is similar to the hemagglutination-inhibition (HAl) technique that is available for erythropoietin. For the production of TSF, sheep were made thrombocytopenic by the Injection of antiplatelet serum. TSF from sheep sera was partially purified by column chromatogr...
Sera from 290 hospital patients were tested to compare the sensitivity, specificity, and reproducibility of the hemagglutination treponemal test for syphilis (HATTS) with the fluorescent treponemal antibody absorption test (FTA-ABS). Complete agreement was obtained between the methods when 142 syphilitic sera from patients with various stages of syphilis were tested. By using clinical histories...
